Secret Letters

Dean comes back from his classes to find an envelope had been shoved under his dorm room door. It contained a love letter not meant for him, and a rather intimate picture. To his shock he realizes he knows the man in the picture. It's his long time crush, Castiel. Without a way to get the picture back to the man, he decides to crash his date, since the man Castiel had invited wasn't coming. It could go one of several ways. Too bad he won't know until he gets there.
